Where to connect the starter?

I'm about to install MS Relay board in my 280z and bypass the fuel and ignition relay. I just want to know where am I suppose to connect the signal wire from the starter? Thanks

The starter doesn't connect to the MS. It goes from the key to the starter. The MS detects startup through RPM.

Starter connects to the battery. At least at one end.

I believe you're asking about how the starter solenoid is energized? MS1/2/3 could have a trigger output for that, but don't bother with that. Just figure out some way to energize the starter solenoid. Follow the skinniest wire attached to the starter solenoid. That skinny wire needs +12v (I think, right...? Or is it ground?) in order to fire up the starter solenoid. Use a momentary switch, for example your ignition switch, or some fancy aftermarket switch. The MS ECU "runs" when you turn the car on, it won't do anything until it "sees" RPM or other signals coming from an engine that's turning over.

Trolling three week old posts to give advice you're not sure about seems a little odd.  Post count pumper?

Battery positive runs to the post on the battery. ( not the one that has a cable running into the body of the starter). Fusible link for vehicle power goes to the same.

 

Starter energize runs directly from the ignition swith to the solenoid post. (Small spade connector between the 2 large posts). This will be a 12v wire and it grounds through the starter
